number of actors to three. When Euripides began to write his terrible tragedies in the middle of the fifth century, B.C., he was allowed as many actors as he liked and when Aristophanes wrote those famous comedies in which he poked fun at everybody and everything, including the Gods of Mount Olympus, the chorus had been reduced to the rôle of mere bystanders who were lined up behind the principal performers and who sang "this is a terrible world" while the hero in the foreground committed a crime against the will of the Gods.
This new form of dramatic entertainment demanded a proper setting, and soon every Greek city owned a theatre, cut out of the rock of a nearby hill. The spectators sat upon wooden benches and faced a wide circle (our present orchestra where you pay three dollars and thirty cents for a seat). Upon this half-circle, which was the stage, the actors and the chorus took their stand. Behind them there was a tent where they made up with large clay masks which hid their faces and which showed the spectators whether the actors were supposed to be happy and smiling or unhappy and weeping. The Greek word for tent is "skene" and that is the reason why we talk of the "scenery" of the stage.
When once the tragedy had become part of Greek life, the people took it very seriously and never went to the theatre to give their minds a vacation. A new play became as important an event as an election and a successful playwright was received with greater honors than those bestowed upon a general who had just returned from a famous victory.
